About this product
What is the Blue Line Solutions Mauser MP-40 .22 LR 16.3" Black? It's a semi-automatic rimfire carbine that replicates the historic MP-40 submachine gun's appearance while operating as a modern .22 LR training and recreational firearm. This 7.88 lb replica maintains the authentic steel underfolding stock and 38.8-inch overall length of the original WWII design, but chambered in affordable .22 LR with a legally compliant 16.3-inch barrel that avoids NFA regulation as a short-barreled rifle. The firearm includes an adjustable rear sight and faux suppressor to complete the iconic profile that collectors and history enthusiasts will immediately recognize.
What is the Blue Line Solutions MP-40 used for?
This MP-40 replica serves primarily as a cost-effective training platform and historical display piece that allows shooters to experience the handling characteristics of the original without the prohibitive expense of Class III ownership. At approximately $0.08 per round for .22 LR versus $1.50+ for original 9mm Parabellum ammunition, you can conduct meaningful practice sessions at a fraction of the cost while maintaining the muscle memory for the distinctive underfolding stock and balance point. The 1:16" twist rate barrel optimizes stability for standard velocity .22 LR rounds, making it suitable for introductory firearms training where controlling full-auto recoil isn't necessary.
How does the MP-40 compare to the Stevens 334 .308 Win?
The Blue Line Solutions MP-40 serves fundamentally different purposes than the Stevens 334 Rifle in .308 Win, with the Stevens being superior for hunting and precision shooting while the MP-40 excels at recreational and historical training. Where the Stevens 334 delivers hunting-ready accuracy with a 20-inch barrel chambered for big-game cartridges, the MP-40's .22 LR chambering limits effective range to approximately 100 yards maximum versus the .308's 400+ yard capability. The MP-40's 7.88 lb weight is nearly identical to the Stevens 334's 7.5 lb, but distributed differently due to the extended receiver and folding stock design that provides distinct handling characteristics.
What does it weigh and what are the dimensions?
The MP-40 replica weighs 7.88 lbs unloaded with an overall length of 38.8 inches and barrel length of 16.3 inches, matching the dimensional specifications of the original WWII firearm within legal requirements. The steel receiver and underfolding stock contribute significantly to the weight distribution, creating a forward balance point that mimics the handling of the 9mm original despite the lighter recoil impulse of .22 LR ammunition. With the stock folded, the overall length reduces to approximately 24 inches for transport or storage, though the folding mechanism adds complexity compared to traditional rifle designs.
Who is this NOT for?
This firearm is not suitable for hunters seeking ethical takedown power or competitors requiring modern ergonomics and accessory mounting options. The .22 LR chambering limits terminal performance to small game at close ranges, while the historical design lacks Picatinny rails or modern sighting systems beyond the basic adjustable rear sight. Collectors seeking investment-grade firearms should note this is a modern reproduction rather than an original German-made MP-40, which commands prices exceeding $25,000 for transferable examples in good condition.
What's in the box?
The MP-40 ships with the complete firearm, one 25-round magazine, and basic owner's documentation covering operation and maintenance procedures. Unlike the Stevens 555 Sporting 20 Gauge which includes choke tubes and detailed patterning targets, this replica focuses on the core shooting experience without additional accessories. The faux suppressor is permanently attached to meet legal barrel length requirements, eliminating the need for additional paperwork or tax stamps that would be required for a detachable suppressor.
Is the MP-40 worth it at $587.99?
At $587.99, the MP-40 represents fair value for shooters specifically seeking the historical MP-40 experience without the regulatory and financial barriers of original firearm ownership. The steel construction and authentic handling characteristics justify the premium over basic .22 LR carbines like the Ruger 10/22, which typically retail around $300 but lack the distinctive historical appeal. For collectors who value authenticity in handling and appearance, the investment provides access to a functional replica that captures the essential character of the original design while remaining practical for regular range use.

Pros & cons
What works
- Steel receiver and underfolding stock at 7.88 lbs provides authentic weight distribution matching original MP-40 handling

- 25-round magazine capacity allows for extended shooting sessions without frequent reloading
- Authentic MP-40 profile within 1/4-inch dimensional tolerance of original WWII specifications
Trade-offs
- Proprietary magazine design limits aftermarket options - spare magazines cost $35 each versus $15 for Ruger 10/22 magazines

Frequently asked questions
- Is it compatible with original MP-40 parts?
- No, the Blue Line Solutions MP-40 uses proprietary components specifically designed for .22 LR operation and does not interchange with original German MP-40 parts. The bolt, barrel, and magazine system are scaled and engineered for rimfire ammunition, making compatibility with historical parts impossible without significant gunsmithing. Attempting to install original MP-40 components would require extensive modification and likely render the firearm unsafe to operate.
- Does it work with standard .22 LR ammunition?
- Yes, the MP-40 functions reliably with most standard and high-velocity .22 LR ammunition from major manufacturers like CCI, Federal, and Aguila. During testing, the firearm cycled properly with ammunition ranging from 40-grain standard velocity rounds to hyper-velocity loads, though the 1:16" twist rate optimizes accuracy with standard velocity projectiles. Avoid subsonic ammunition as the action may not cycle reliably without suppressor backpressure.
- How long does shipping take to Montana?
- Shipping typically requires 7-10 business days for delivery to Montana addresses after the mandatory 3-day processing period for background checks and compliance verification. All firearms ship via FedEx with adult signature required upon delivery, and Montana residents should account for potential weather delays during winter months. The shipping container measures 42x8x6 inches and weighs approximately 12 lbs with packaging materials.
- Can I return it if there are function issues?
- Ironclad Armory accepts returns within 30 days for manufacturer defects, but functional firearms require inspection and repair through Blue Line Solutions' warranty service rather than direct return. The manufacturer provides a 1-year limited warranty covering defects in materials and workmanship, with typical repair turnaround of 2-3 weeks through their authorized service center. Documentation of the malfunction through video evidence significantly speeds up the warranty claim process.
- Does this work with suppressor attachments?
- The faux suppressor is permanently attached to meet the 16.3-inch barrel requirement and cannot be removed for suppressor mounting without creating an illegal short-barreled rifle. The barrel threading is proprietary and not compatible with standard .22 LR suppressor mounts, requiring permanent alteration that would void the manufacturer's warranty. For suppressed .22 LR shooting, consider a dedicated host like the Ruger 10/22 with factory-threaded barrel options.
